Definitions

  • the invention relates to a bogie for rail vehicles, in particular for high speeds, consisting essentially of a lower torsionally designed guide frame connecting the bearings of wheel sets, springs arranged above these bearings, on which the vehicle body with the interposition of supporting bodies connected by an upper swivel frame around a vertical axis is rotatably supported, wherein elements for transmitting longitudinal and transverse forces are arranged between the guide frame and the swivel frame.
  • the bearings of the wheel sets connected by the lower guide frame are arranged on the outside of the bogie in front of the corresponding wheel.
  • the springs located above these bearings support the vehicle body with the interposition of the supporting bodies each provided with raceway segments, these supporting bodies replacing a slewing ring construction in their connection by the upper swivel frame.
  • Corresponding trailing arms and wishbones are provided as elements for transmitting longitudinal and transverse forces between the lower guide frame and the upper pivot frame. Due to the above construction, a development direction to a bogie for higher speeds is shown because of the reduction in the bogie mass that can be achieved without a conventional weight-consuming bogie frame.
  • the invention has for its object to provide for a bogie of the generic type with the least possible structural effort for optimal running properties even at particularly high speeds and low wear on the wheel and rail; For this purpose, the unsprung masses in particular should be reduced and a largely torque-free power transmission should be achieved.
  • This object is achieved in that on the guide frame for guiding the wheelset whose wheels are each fastened with two arms fork-shaped brackets, that the two arms of each bracket for receiving bearings for a wheel-fixed, lengthwise only according to the distance of these bearings extending support part are formed so that each bearing is supported by a spring arranged in its vertical axis against the swivel frame, and that the fork-shaped holder is connected to the guide frame by means of a fork head connecting its two arms with the interposition of an elastic connecting element, for example a rubber bushing.
  • the state of the art also includes a bogie, in which the vehicle body - deviating from the genre and solution of the subject matter of the invention - does not have springs directly on the bearings of the wheel sets, but has a secondary suspension (air springs) and one Primary suspension is supported.
  • the H-shaped frame of this known bogie has brackets encompassing the wheels of wheel sets, each of which is designed to accommodate bearings for wheel-fixed supporting parts that only extend in length according to the distance between these bearings, each holder having an outside the bearing arranged spring is supported against a cross member which extends between the ends of side supports of the H-shaped frame.
  • the side beams and the cross beams as well as the brackets are subjected to bending; This leads to an undesirably high weight of the bogie for the running properties and wear on the wheel and rail and a large mass moment of inertia around the bogie vertical axis.
  • the limitation of the supporting parts of the wheel set to the area of each wheel and the mounting of these supporting parts provided on each side of the individual wheel ultimately on the swivel frame advantageously result in a significant reduction in the unsprung masses for optimal running properties and low wear and allows direct, largely torque-free power transmission in the Vehicle body a weight-less favorable design of both the guide frame and the swivel frame.
  • the elastic connecting element arranged between the fork head of the holder and the guide frame advantageously serves to dampen vibrations and noises and to achieve radial adjustments of the wheels when the bogie is cornering; In addition, the elastic connecting element absorbs and removes part of the twists that occur, for example, due to unevenness in the rail system.
  • the torsionally strong management framework is a burden.
  • the holder with its fork head connecting the two arms is furthermore cheap to produce as a ready-to-install assembly and can be used with different bogies in terms of dimensions, in particular with regard to the track width.
  • the bearings for the wheel-fixed supporting parts each from one formed on the arms of the brackets fixed housing part and consist of a detachable housing part, the separation point between the fixed housing part and the detachable housing part is arranged inclined with respect to the vertical transverse plane of the bearing such that a receptacle for the in Vertical axis of the bearing located spring is attachable.
  • the springs supporting the vehicle body are flexicoil springs, it is advisable according to a further development according to the invention that the arms of the fork-shaped holder or the fixed housing parts of the bearings formed on the arms are provided with a centering for the respective flexicoil spring.
  • hydro-pneumatic springs can be used to support the vehicle body, which also act as dampers.
  • a supplementary feature according to the invention provides that the arms of the fork-shaped holder or the fixed housing parts of the bearings formed on the arms have a fork-shaped attachment for fastening a bearing eye of the respective hydro-pneumatic spring.
  • a next embodiment of the invention is that the fork-shaped holder is designed to accommodate a disc brake arrangement acting on the corresponding wheel.
  • a bearing point is arranged on the fork head of the holder as a fixed point for a pair of caliper brakes acting in the region of the horizontal axis of the wheel, the arms of the bracket each being provided with a recess serving for the passage and the support of the caliper brake pair are.
  • the guide frame consists of two angularly designed, mutually identical frame parts which are connected to one another via joints designed according to the required torsion ability.
  • the supporting bodies are arranged in the vertical axis of each spring.
  • rubber-sprung intermediate pieces are arranged between the vehicle body and the supporting bodies, these intermediate pieces being designed in segment form according to a next inventive feature.
  • hydraulic cylinders are articulated on the swivel frame in a three-point arrangement for height-adjustable suspension of interconnected rail brake bodies.
  • each rail brake body is guided in a height-displaceable manner in a transmission part connected to the guide frame for the braking forces which occur, the transmission part being designed as a tear-off protection for the rail brake body .
  • the support parts at their ends pointing towards the bogie longitudinal center for the connection of a mutual connecting piece, for. B. a thin-walled spacer tube, gear or a brake are set up.

  • the rollers 16a interact with treads on the vehicle body, which are formed by rubber-sprung, segment-shaped intermediate pieces 17.
  • the swivel frame 6 is connected to the vehicle body via a bearing 15 arranged in the vertical central axis of the bogies shown in a horizontally rotatable manner.
  • This bearing 15 determines the swivel radius for the rollers 16a of the support body 16 and is used to transmit longitudinal and transverse forces.
  • the longitudinal forces pass through the link 22 (see FIG. 2) and the lateral forces via the flexicoil springs 5a with parallel dampers 23 (see FIGS. 1 and 3) from the guide frame 1 onto the pivot frame 6 and thus into the bearing 15.
  • the bearing 15 is correspondingly extended downwards to form a deep linkage (see FIGS. 4 and 5), provided with a crosshead 15a and connected to the guide frame 1 via coupling arms 15b; lateral forces that occur are transmitted via hydro-pneumatic components 24 (see FIGS. 4 and 6).
